BALL-BEARING.

SPECIFICATION forming part of Letters Patent No. 583,911, dated June 8, 1897.

Application filed October 9, 1895. Serial No. 565,200. (No model.)

. able others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in ball-bearings for vehicles and other wheels; and its novelty and advantages will be fully understood from the following description and claim when taken in conjunction with the annexed drawings, in which- Figure 1 is a diametrical section of a hearing embodying my invention. Fig. 2 is a transverse section taken in the plane indicated by the line m a; of Fig. 1, and Fig. 3 is an elevation of the sleeve which receives the axle-spindle.

In the said drawings similar letters designate corresponding parts in all of the several views, referring to which A indicates a vehicle -axle which has a spindle 0:, provided with a reduced and threaded outer end I), and also has the narrow shoulder a and the circular enlargement d, and B indicates the sleeve or box, which loosely receives the spindle. This sleeve or box Bis exteriorly threaded at its outer end, as indicated by e, and it is provided at its innor end with the circular enlargement f, which receives the shoulder a and enlargement d of the spindle and forms the interior shoulder g, which bears against the shoulder a and is preferably grooved, as shown, to better hold the lubricant, and the exterior shoulder h, for a purpose presently described.

0 indicates a ring which is mounted on the threaded end 6 of the sleeve or box B and has a fiat inner side, as shown.

D indicates an annulus which is mounted on the sleeve B at the inner side of the ring G, and E indicates an annulus which is mounted on the sleeve or box and arranged against the shoulder h thereof. The annulus D and the annulus E are of a general right'angled form in cross-section, as shown, to conform to the sides of the ring 0 and shoulder h and the sleeve B, and they are respectively provided in the outer sides of their horizontallydisposed portions at the inner ends thereof with grooves '1; of curvilinear form in crosssection, which are designed to form part of raceways for antifriction-balls F, as will be presently described.

G H indicate cups which surround the annulus D and annulus E, as illustrated. These cups G H, respectively, comprise the horizontally-disposed portion j, the outwardlyextending portion k at the outer edge of the horizontal portion, which is disposed at right angles to said horizontal portion, and the inwardly-extendin g portion Z at the inner end of the horizontal portion ,7, and they are pro vided in their inner sides at the junction of the horizontal and inwardly-extending portions with grooves m of curvilinear form in cross-section, which serve, in conjunction with the grooves 11 of the annulus D and the annulus E, to form the raceways of the antifriction-balls F, of which any suitable number may be employed. In addition to serving in conjunction with the annulus D and annulus E to form raceways for the balls F and retain said balls in position the cups G H serve to hold the metallic wheel-hub I in position. This hub I is a plain cylinder,which has outwardly-extendin g flan ges p at its ends, provided with apertures q for the passage of bolts, (not illustrated,) which serve to retain spokes (not illustrated) between the flanges, and it is held in position by the cups G H, as stated, and serves in turn to hold said rings in their proper position with respect to the annulus D and annulus E, as shown. As will be readily observed, the peculiar shape of the cups G H and the huh I obviates the necessity of recessing and thereby weakening the hub, which is an important advantage.

J indicates a nut which is mounted on the reduced end 12 of the spindle A and preferably has its inner side recessed, as shown, to receive the outer end of the larger portion of the spindle, as shown. This nut J abuts against the outer end of the sleeve 13 and serves to retain said sleeve upon the spindle, and it is provided with a circumferential flange 0', between which and the annulus D is interposed a ring K. rounds the ring 0 and the joint between the nut J and sleeve B, and serves, in addition The said ring K sur-' to assisting in holding the annulus D in position, to prevent the entry of dust between the sleeve B and spindle a of the axle.

It will be readily observed from the foregoing that the nut J serves to retain the sleeve B and all of the parts thereon upon the spindle a, and that by simply screwing the said nut off, the sleeve and all of the parts thereon maybe readily removed from the spindle without any of said parts being disconnected. It will-also be seen that the several parts upon the sleeve 13 may be readily removed therefrom for the purpose of repair or replacement when the threaded ring 0 is screwed off the threaded end of the sleeve and may bereadily replaced upon said sleeve and secured thereon, which is an important advantage.

It will further be observed that in my imon the said spindle and having exterior threads at its outer end and also having the enlargement at its inner end forming an interior shoulder and an exterior shoulder, a nut arranged on the reduced and threaded end of the spindle and abutting against the end of the sleeve,a cylindrical hub surrounding the sleeve, the cups G, H, having the horizontally-disposed portions arranged Within the hub at opposite ends of the same, the outwardly-extending portions at the outer edges of the horizontal portions bearing against the ends of the hub and the inwardly-extending portions at the inner edges of the horizontal portions, an interiorly-threaded ring 0, mounted on the threaded end of the sleeve, an annulus D, mounted on the sleeve and arranged against the said ring, an annulus E, mounted on the sleeve and arranged against the shoulder thereof, antifriction-balls interposed between and arranged in raeeways formed by thecup H, and the annulus E, and the cup G, and annulus D, and the ring K, surrounding the ring 0, and interposed between the nut and the annulus D, all substantially as and for the purpose set forth.
